Pityriasis Versicolor

Pityriasis versicolor or tinea versicolor is a common yeast infection of the skin, in which flaky discoloured patches appear on the chest and back. Pityriasis versicolor most frequently affects young adults and is slightly more common in men than in women. It can also affect children, adolescents and older adults. Pityriasis versicolor is more common in hot, humid climates than in cool, dry climates. It often affects people that perspire heavily. It may clear in the winter months and recur each summer.

It is often discovered by the appearance of lighter colored spots of the skin, they can be see in darker skin types or during summer when skin tans in color. These spots can be itchy or asymptomatic. The rash often presents on the chest and back but can spread to involve the face, neck and arms.

This condition is treated by topical antifungal medications. Oral antifungals may be necessary in severe cases, but caution should be used for prolonged term usage. This dermatitis does tend to recur in the summer months and is often made worse in warm or humid enviornments.
